Abstract: A study of the estimation of seismic demands of three-dimensional buildings with bi-axial eccentricity in a plan subjected to two components of ground motion is investigated. Their estimates are compared to the exact results obtained from nonlinear time history analysis. The selected procedures are: extended N2, modal pushover analysis (MPA), modified MPA (MMPA), practical MPA (PMPA), Multimode pushover and response spectn analysis (RSA) extended to bi-directional excitation. A three-story asymmetric building subjected to different bidirectional exits is considered. It is shown that the accuracy of the above-mentioned procedures results depends on the type of considered ground motion
